"Fundamental change"

That is getting to be a really ugly phrase from government officials. And it isn't just our president; it was building long before he set his cap for becoming the most powerful man on the plant. I saw it today in a JAMA editorial, "Extra calories cause weight gain--but how much?" The up side is, no one knows. The down side is, the government will take action anyway.

There's a lot of interesting detail in this editorial. For instance, in the 1970s women age 20-29 had a mean body mass of 23; 30 years later the same group had a BMI of 29, representing a weight gain of 35 lbs (16 kg). I've been to a lot of class reunions over the years, and I'd say that's shy 10 lbs or so.

Also, did you know that in theory if you ate just one more chocolate chip cookie each day, you'd gain hundreds of pounds in your life time? But you don't. Why? Because after you reach a certain weight, it takes a lot of those cookie calories just to maintain your weight gain. The same principle applies to weight loss through calories restriction and increased exercise. That same body will attempt to conserve energy, and after you reach your goal and go back to eating normally, you gain weight rapidly.

[Pause here to wipe off my fingers--I'm eating chips.]

So the conclusion after weighing all the evidence is,
    "An effective public health approach to obesity prevention will require fundamental changes in the food supply and the social infrastructure. Changes of this nature depend on more stringent regulation of the food industry, agricultural policy informed by public health, and investments by government in the social environment to promote physical activity."
Last night for dinner I had one skinless chicken thigh, baked, beans and rice, fresh strawberries -- and two donut holes. I'd had my other fruits and veggies earlier in the day. Just let the government come knocking at my door for those donut holes.
